Abstract: PURPOSE:To quickly operate a temperature oven-rise preventing element when the temperature of a fixing roller is overrisen with the abnormality of a temperature control circuit by using a bimetal plate as the supporting member of the temperature overrise preventing element. CONSTITUTION:This temperature overrise preventing device 11 is laid on the fixing roller 1, and the temperature overrise preventing element 12 of the device 11 is supported by a supporting member 14 so as to come into contact with the fixing roller 1 when its temperature is an ordinary one. The supporting member 14 is made of a material so as to be deformed by a change in the temperature of a bimetal, a shape storage memory alloy, etc. The supporting form of the temperature overrise preventing element 12 by the supporting member 14 is set as follows. In other words, time until tone temperature over-rise preventing element 12 is separated from the fixing roller 1 after warming up is started, is set about the same as that until a heating source 3 consecutively supplies power after the ordinary temperature is obtained, in a state where the element 12 comes into contact with the fixing roller 1, and the element 12 is operated. Therefore, the element 12 comes into contact with the fixing roller 1 at the time of overrising the temperature, so that quick correspondence can be attained.

Title: Formation of groove and dielectric isolation region
Inventor: KATO HISAYUKI
IPC: H01L21/76
Filed: 1984-12-24
Abstract: PURPOSE:To enable to integrate highly an LSI or VLSI, by forming the opening corner of a groove in a tapered shape and by etching deeply the groove bottom to a predetermined depth with anisotropic dry etching. CONSTITUTION:On a silicon substrate 1, thermal oxidizing forms an SiO2 film, on which an Si3N4 film 3 is formed as a first mask. Next, a groove is patterned and the silicon substrate 1 is etched vertically to form a shallow groove. A CVD-SiO2 film 5 is formed thickly and is then etched back with dry etching so as to expose the Si3N4 film 3, forming an opening corner 6 of the groove 4 in a tapered shape. Next, anisotropic dry etching more deeply etches the bottom of the groove 4 in the silicon substrate 1. Thus the CVD-SiO2 film 5 formed on the side wall of the opening portion of the groove 9 can block incident ions when etching the bottom to prevent side etching, so that the vertical deep groove 9 with a narrow width can be formed easily and precisely in the silicon substrate 1.
